how to disable the Selected tree Node in Asp.net pages or SharePoint 2010 Webpart

We should Not allow the user to click twice on the same node.because it cause post back

Solution:
 - -> Pass the root Node value as a parameter
// Method for Going all Nodes and setting the Enable and disable
    protected void ParseNode(TreeNode tnRootNode)
        {
            if (tnRootNode.Selected)
            {
                tnRootNode.SelectAction = TreeNodeSelectAction.None;
            }
            else
            {
                tnRootNode.SelectAction = TreeNodeSelectAction.Select;
            }
              
            foreach (TreeNode child in tnRootNode.ChildNodes)
            {
                if (child.ChildNodes.Count > 0)
                {
                    ParseNode(child);
                }
                else
                {

                    if (child.Selected)
                    {
                        child.SelectAction = TreeNodeSelectAction.None;
                    }
                    else
                    {
                        child.SelectAction = TreeNodeSelectAction.Select;
                    }
                }
            }

Automation Server cant create An Object Error in SharePoint 2010

Problem:

 When try to validation in File upload control as regular expression it shows automation server cant create object Error.

solution:
In Internet Explorer, click on Tools -> Internet Options -> Security Tab and then under "Security level for this zone" click Custom Level... Locate the "ActiveX controls and plug-ins" section and then set "Initalize and script ActiveX controls not marked as safe for scripting" to "Prompt" which will force IE to prompt you for approval when an ActiveX control that is not marked as safe (such as WScript) attempts to be called.

Back up and Restore the site collection using stsadm command in SharePoint 2010

When you back up by using the Stsadm command-line tool, you can back up individual aspects of your SharePoint Products and Technologies deployment. For example, you can back up an individual site collection or you can back up the entire farm.

To export sites from your SharePoint Products and Technologies deployment, you use the following Stsadm command.

Stsadm –o export –url <URL> -filename <FileName>.cmp

To back up a site collection, you must use the following stsadm command.

stsadm –o backup –url <URL of the site collection> -filename <Name of the backup file> 

To back up an individual database, Web application, or the entire farm, you can use the following Stsadm command.

stsadm –o backup –directory <UNC path or local drive> -backupmethod <Full or Differential>

Restore

To import sites to your SharePoint Products and Technologies deployment, you use the following Stsadm command.

Stsadm –o import –url <URL> -filename <FileName>.cmp

To restore a site collection, you must use the following Stsadm command.

stsadm –o restore –url <URL of the site collection> -filename <Name of the backup file> 

To restore an entire farm you can use the following Stsadm command.

stsadm –o restore –directory <UNC path or local drive> -restoremethod <overwrite or new>

Can not connect to configuration database (error) in SharePoint

Here are some method to resolve this error taken from the Microsoft support site.i faced this problem and after restart of my MS SQL service for Sharepoint it works. So first please try Restarting the MS SQL service then you can follow the below steps

 

 

Method 1: Verify that the SQL database is running

1. Click Start, point to Programs, point to Administrative Tools, and then click Services.
2. In the list of services, locate the MSSQLSERVER service. This service may also be listed as MSSQL$SHAREPOINT.
3. Note the value of the Status column. If the Status column lists Started, the database server is running. If the Status column is empty, the database server is not running.
   
   To start the database server, right-click the MSSQLSERVER service, and then click Start.

Method 2: Verify that IIS is not running in IIS 5.0 isolation mode

1. Click Start, point to Programs, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.
2. In the left pane, right-click your server name, and then expand the local computer.
3. Right click Web Sites, and then click Properties.
4. Click the Service tab.
5. Click to clear the Run WWW service in IIS 5.0 isolation mode check box.
6. Click OK
7. To start the WWW service, click Yes.

Method 3: Make sure that the account that is used by the application pool is the account that has the required permissions to the SQL Server database

First, you must first determine the application pool identity. To do this, follow these steps:

1. Click Start, point to Programs, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.
2. Double-click the Web Sites folder.
3. Right-click the virtual server that is running Windows SharePoint Services 2.0, and then click Properties.
4. Click Home Directory.
5. Note the information that is in the Application name box (this is the application pool name), and then click Cancel.
6. In the left pane, right-click Application Pools, and then click Properties.
7. Click the Identity tab.
8. Note the information that is in the Application pool identitypane, and then click Cancel.

Next, you must verify that this account has the required permission the SQL Server database. To do this, follow these steps:

1. Click Start, point to Programs, point to Microsoft SQL Server, and then click Enterprise Manager.
2. In the left pane, double-click Microsoft SQL Servers, and then double-click your SQL server group.
3. Double-click your server.
4. Double-click Security.
5. In the left pane, click Logins.
6. In the right pane, double-click the user who you noted step 8 of the previous procedure.
7. In the SQL Server Login Properties dialog box, click Server Roles.
8. Click to select both the Security Administrators and the Database Creators check boxes, and then click Database Access.
9. Under the Permit column, click to select the Windows SharePoint Services database.
10. Click OK.

Method 4: Make sure that you have network connectivity and correct name resolution between the servers

To do this, follow these steps:

1. Verify that the Windows SharePoint Services server is using the correct IP address for the SQL server. To do this, run the ping command on the Windows SharePoint Services server.
2. Verify that the Windows SharePoint Services server is obtaining the correct IP address for the SQL server from DNS. To do this, run the nslookup command from the Windows SharePoint Services server.
3. Make sure that there are no incorrect entries for the SQL server. To do this, examine the Hosts file on the Windows SharePoint Services server. This file is in the following location:
   %systemroot%\system32\drivers\etc\Hosts
4. On the Windows SharePoint Services server, look for SQL client aliases. To do this, follow these steps:
   1. Click Start, click Run, and then type cliconfg in the Open box.
   2. Click the Alias tab.
   By default, there are no SQL client aliases. If you have any aliases for the SQL server, verify that they are correct, or remove them.

Here three Methods are there ,using these three methods we can read excel data and store into a list or Table.

Please create a Excel based on your table column name or list column name.

First row of excel sheet it will use as a header column name and then data will be read.

Hope this is enough ....if any problem comes please let me know 

Join Operation between Lists in SharePoint 2010 using SPMetal and LINQ to SharePoint

Required class:

Entity Class generated using SPMEtal.exe

Procedure To create Entity class:

     create a text file and copy following text in green

set SPMETAL="C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN\SPMETAL.EXE"
%SPMETAL% /web:http://sitename/ /namespace:SharePointLINQ.JoinLists1 /code:EntityClass.cs

pause

Add the entity class into your sharepoint project solution

Add the reference of the class in project

join Operation between two or more  list using Entity class:

Where the item is returning null give some value either empty string.... Very very important
